Question

If Y= {x:x is a positive factor
of the number 2^p-1 (2^p-1),
where 2^p-1 is a prime number}
Write Y in roaster form​

Answer 1

Step-by-step explanation:

The given set Y = {x:x is a positive factor of the number , where 2p - 1 is a prime number}

There are only two positive factors of the number and 1

[Since, it is given that 2p – 1 is a prime number.]   

Hence, Y in Roster form:

Roster form is a representation of the elements in the set separated by commas.

Answer 2

Step-by-step explanation:

number 2p – 1 (2p – 1), where 2p – 1 is a prime number}. Y- {x | x is a positive factor of the number 2p-1 (2p – 1), where 2p – 1 is a prime number}. So, the factors of 2p-1 are 1,2,22 ,23 ,…, 2p-1 . Y= {1,2,22 ,23 , …,2p-1 ,2p -1}
